INT 13H 0aH: Read Sector Plus ECC
Expects: AH 0aH
AL sector count (usually 1)
CH track (cylinder) number (0-n) <Ķ»
CL sector number (1-n) <ĶĶĶĶĶĶĶĶĶĶĶŹĶĶ (see below)
DL drive: 80H-81H=hard disk 0-1
DH head number
ES:BX caller's buffer address
Returns: AH BIOS disk error code if CF is set to CY
Info: This works just like the standard Read (INT 13H 02H), except that
four to seven bytes of data (the ECC^ or Error Correction Code
bytes) follow the contents of the sector.
CX Bits 6-7 of CL are the high two bits of the 10-bit value whose
low 8 bits are in CH. See INT 13H 02H for details.
Notes: ž This is typically used only by diagnostic software.
ž On a multiple-sector operation, this returns without finishing
the read when it encounters an error.
